I'm getting error with the tooltip when redraw DualY Chart.

[Kha Nguyen Dong]

I'm developing statistic app using MVC. I click Submit to draw chart in the first time and hover on it's column.

But when I click Submit again redraw the chart, I hover the column and it disappear, and it's tooltip seem like error.

Can someone show me the solution to solve this problem?

[Sergey Grabkovsky]

Hi Kha,

It's hard to say what's going on without any code that reproduces the issue. My guess is that either there is a better way to redraw the chart than what you're currently doing, or that the issue is fixed in version 43.

Thanks Sergey,

I stored the code to draw chart and statistic's template in a PartialView. I use ajax to load  the PartialView and insert it in a DIV. When i click submit again, I empty the DIV add insert the view into it again.

the problem only happen when I draw chart => hover the column => redrawn => hover the column again.

I think the chart need to be destroyed before I redrawn the new chart.

Hope you can help me.

Here is my code:

I can't use your code when it's as a screenshot, please attach a text file. The code you screenshotted also doesn't appear to contain the part that you said actually causes the error, which is the chart redrawing. However, if that's your method for redrawing the chart, then the issue is that you create a new instance of the chart every time you redraw, where you should reuse the previous instance.

Hi Kha,

I don't have a Windows machine immediately available, nor do I have Visual Studio installed on the Windows machines I do have. So I wouldn't be able to run your app if I wanted to.

This is the kind of example I meant. If you can modify that example to reproduce the issue you're experiencing, I can tell you whether it's a bug or user error.

Hi Sergey,

I'm sorry, I'm too busy so I forgot to respond to you. I replace my code into your example, it worked without any bugs and I don't know why? I met another error "Object doesn't support property or method Contains" in IE, I fixed it by using frozen version v41. Luckily, the bug when redraw the chart was fixed.
